Application filed June 12, 1922, Serial No. 567,829, and in France August 3, 1921.

the latch into the staple will set up a reaction having a component which is perpendicular to the door, thereby providing for the complete closing of the door and the tight holding of the automatic manner, wear of the parts.

Another particular feature of the invention results from the combination of the fastening device with the door holding device according to the United States Patent No. 1,441,530, dated January 9,1923.

The following description, together with the accompanying drawings which are given by way of example, sets forth an embodiment of the invention.

Fi 1 is a front view of the interior of the astening device in the closed osition.

Fig. 2 is a section on the line X- Fig. 1.

Fig. 3 is a side view of the fastening device in the closed position.

Fig. 4 is a side view of the portion-of said device carrying the door latch and disposed upon the door leaf.

Figs. 5, 6 and 7 are three diagrammatic views explaining the o eration of the inclined plane of the latch.

Fig. 8 is a diagrammatic view showing the operation of the latch in case of wear.

In the form of construction indicated in said figures, the fastening device is composed in the known manner of two parts, the portion a comprising the staple which is cast in one piece and is mounted on the door frame, and the second portion 12 secured to the door leaf and comprising the latch and the operating devices for the same. The portion 1) is constituted by a plate I) bent at a right angle and is screwed to the door leaf. It has disposed upon the internal surface, on the inner side of the door leaf, the

closing device in an irrespectively of the frame 0 wherein is slidable the latch d. A

spiral spring a has one end secured to the portion 1; and bears at the other end e u on a projection (27 of the latch whereby the atwhich has ter shall be constantly impelled towards the exterior into the position correspondmg to the door closing. A lever f pivoted at to the plate I) is caused toact upon the PI'OJGCtlOIl d of the latch in order to slide the latch within the frame, said lever being terminated by a knob of any suitable kind which is disposed in the known manner on the upper rim of the door.

The cam 71. is provided with a knob disposed at the exterior and at the same height as the fastening device, and it acts upon the lever f through the medium of a sliding member 72 Fig. 1, disposed between the plate 6 and the frame 0 of the latch, and

the door can thus be opened or closed by means of the knob disposed upon the cam 12.. A spiral spring g is secured at one end to a stud on the plate b and acts at the other end upon the nib f of the lever f in such manner that when the door is closed the said lever will be caused to bear upon the sliding member h, and this will obviate all rattling of the lever f and of the cam h which would result from the jarring movements.

The portion a secured to the door frame is formed in a single piece wherein is pressed the staple and the female portion or mortise i of the door holding device. When the door is closed, the conical male portion 11 which is cast integral with the plate b will engage the said mortise. The conical male portion 2' and the mortise i constitute the device set forth in applicants United States Patent No. 1,441,530, dated January 9, 1923.

The particular feature of the resent invention consists in the fact that t is, Fig. 2, of the door latch is not parallel to the plane of the door but is somewhat inclined to the latter, as observed in Fig. 2 and Figs. 5 to 7, and the same is true for the surface 71 of the staple 7', Fig. 2. It will follow that upon closing the door, that is, on passing from the position Fig. 5 to the POSI- tion Fig. 7, the end I of the nib of the latch d will engage the inclined plane I0 Fig; 6, somewhat before the door is entirely closed. At this moment, the spring e which impels the latch into the staple will exert a force upon the inclined plane whereof the reaction comprises a component perpendicular to the plane of the door, and this will tend to bring the door into the closed position as well as to hold the conical member 13 tightly within the mortise i of the door holding device. By

e surface the said arrangement, the door willbe closed and held tight in an automatic manner.

Furthermore, after being in use for some time, the surface In of the staple will become more or less worn. But an increased wear of the staple j will permit the latch to be in-- sorted to a correspondingly greater degree, and as by reason of the inclination of the surface is the end I of the latch will have a beveled form, the more the latch is driven in, the greater will be the thickness of the portion engaging the staple 7', so that the wear is automatically taken up and the male conical ortion i will remain tightly held within t e aperture or female cone 2'. This arrangement is shown in Fig. 8, wherein the position of the latch before the wear of the staple is indicated by the broken lines, and

after the wear by the full lines.

Another advantage of said arrangement consists in the fact that when the door is pushed in order to close the same, it will no on er rebound without giving time for the late 1 to enter the staple, as is the case with the known door devices, but will now close in amore reliable manner inasmuch as the latch can be inserted into the staple with the greatest facility.

It is obvious that the said device is susceptible of all desired modifications in detail without departing from the principle of the invention.

ture to receive and be engaged by the stud when the door is closed, a latch bolt slidably'mounted in the metallic member and having its latching end beveled on its inner face, means on said metallic member for operating said bolt, said staple having a bolt receiving recess provided with an inclined inner face corresponding with the beveled end of the bolt, sald operating means including ,a spring for projecting the latching end of the bolt into the recess and maintaining the beveled inner face of the bolt in constant contact with the inclined face of said recess, whereby the conical engaging surfaces of the aperture and stud are maintained in constant contact by the latch irrespective of the amount of wear of the latch and stud, and movement-of the door in approximately rectangular directions when closed is prevented.

In testimony that I claim the foregoing as my invention, I have signed my name hereto.
